Hi,

How would I be able to tell, if the neighbours where accessing my wireless
connection, I would assume that the connection would be slower, however is
it possible to tell if someone of accessing my wireless connection, is there
any free software to download which could monitor this?

Regards,

The easiest way is to go into your router logs, dhcp logs, your wireless
logs, etc.

Assuming you are using DHCP for all the clients, pc, laptops, etc ...both
wired and wireless ... you should be able to identify all your machines -
either by host name or MAC address. If there is something you don't
recognize - that may be your neighbor.

I use LinkLogger (www.linklogger.com) to track all of my router traffic.
This is not wireless specific - but tracks all activity going in and out of
my router.

Airsnare and it's free.

You probably wouldn't notice the speed depending on what they were
doing.

Have you configured any security whatsoever? MAC filtering is not
considered security.

Turn on WPA with a non-trivial passphrase, and be assured that they
aren't accessing it.

My linksys router allows more than 60 devices without a reduction in
speed.if your neighbour can access your wireless,who cares??

What's your upstream speed and what happens to your downstream speed if
your upstream is saturated? If you haven't tried it, do so then you
will have answered your own question.

That's just one reason why you might care.

Do you have a good solicitor?

You may find that you have the responsibility for any criminal activity
that takes place on that network, whether it be launching a hack attack
or downloading illegal pornography.

If he can access your WiFi, he can break into your LAN computers and
steal your {identity, credit card numbers, passwords, money}. Other
than that, no problems at all. Oh, wait, even an unsophisticated user
can give you viruses and other malware.

The software used is highly dependent on the make and model of your
wireless router, which you didn't supply. Most rely upon the router
to generate SNMP traps. See:
http://svs.sv.funpic.de
http://www.wallwatcher.com
http://www.linklogger.com
for examples.

There are also traffic sniffers. These watch the traffic in and out
of your wireless, usually between your broadband modem and your
router. If something new appears, they will detect it. For example:
http://home.comcast.net/~jay.deboer/airsnare/
http://www.ethereal.com
There are also commercial IDS (intrusion detection systems). Most are
not free, but you can probably bludgeon Arpwatch into some form of IDS
by detecting new IP addresses.
http://linuxcommand.org/man_pages/arpwatch8.html
If you have an integrated modem/router/wireless box, a sniffer will
NOT work because there's no place to sniff traffic. With a sniffer,
you will also need to use a hub, not a switch to sniff the traffic.

If your wireless router supports SNMP, various MIB browses and SNMP
monitoring tools can be used to count connections. I use MRTG or
RRDTool to graph the traffic and number of connections.
http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/
There are lots (and lots) of free SNMP monitoring tools available:

Ooops. I forgot about Syslog monitors. Link Logger uses Syslog, not
SNMP traps. Other free syslog monitors are:
http://www.linklogger.com
http://www.kiwisyslog.com/products.htm#syslog
http://www.winsyslog.com (free version)
More of the same:
http://www.practicallynetworked.com/support/syslog.htm
http://www.softpanorama.org/Logs/Syslog/syslog_for_windows.shtml
As with SNMP, the router or wireless access point needs to support
syslog.

Although I do have to say that the sentence which states "the owner is
ultimately responsible" could still be subject to legal attack.

Does it also therefore follow that if you leave your car unlocked and it
is stolen and used for illegal purposes that the original owner is
responsible for the actions that follow?

It's a weak accusation on from the CPS at best but as ever, unless
properly tested, quotes like that will remain.

David.

Not necessarily.

If a car is "taken" it is no longer possible for the owner to control
it's use whereas the "network" is still under the control of it's owner
and he can control it's use, wonderful things on/off switches.

If he knows that his network has been taken. At what point does every
purchaser of a home wireless box have to become fully IT trained?

What about the use of their malware infected machine for other crime
purposes that aren't even related to wireless? Is the home user
"responsible" because they didn't buy antivirus/malware products or
regularly patch their machine?

I understand where you're coming from, I just think that it's
unreasonable to expect everyone to act in the manner which the CPS seem
to think is suitable. It's just not going to happen.

This is the fundamental principle of "reasonable doubt" though I don't
think that it would exist for a prior kiddie porn offender to try that
claim to doubt when caught again. As ever, it all depends on the
quality (and cost) of ones legal defence.

I haven't had any neighbors try and log on but that may be due to the fact
that I don't broadcast my SSID, have MAC filtering enabled and use WPA
security.

When I have family and friends over who try and log-on using their laptops
the program immediately notifies me of the attempt. It then allows me to
tag them as friend or foe.

The program also allows me to use the routers built-in security to deny any
traffic not tagged as friendly or pre-approved.

A freeware tool I use (but may not work with all products like the one
listed above) is WallWatcher. Only works for Windows. I thas an annoying
tendancy to need to be restarted every few days, just seems to hang. But
I've been happy with it. It does all I really care about. Of course I don't
really care if a neighbor gets on my network. I've applied basic WPA
security, but nothing a determined attacker couldn't get through if he
decided to target me rather then the open networks around me.

fundamentalism, fundamentally wrong.

Remember before this gets to legalistic, we might be talking two different
legal systems, the news article posted was refering to the UK and not the
US. As a result 'reasonable' may have different meanings as applied in a
discussion like this where we are all arm chair shysters.
